From the introduction:
The Black Breath of Iuz is a terrible affliction that has ravaged the Shield Lands for nearly a year now. Was the plague moves across the lands, wiping out peasant and noble alike, hope fades from the once proud eyes of the Shield Landers. But in a sea of darkness rests a glimmer of hope. A cure for the plague may exist. A specially selected army regiment has been constructed to travel to the mysterious Sidhee forest in hopes of finding this cure.
